Try a search of this site. There are hundreds if millions of threads regarding laminators.
Okay maybe only a million or so. Should actually be a "sticky".
In the end it boils down to how much you have to spend or don't want to spend. From what I've read the Chinese laminators work quite well.
Remember:
Laminating is an art not a science. You
will have to learn the proper set-up and operation then
learn your particular rigs idiosyncrasies.
You could have ten of the exact same laminators and all ten will more likely than not run differently.
We have our 65" RS tweaked out and a rather ahh...unique infeed to run 60+ feet with 1/8" drift. Took a long time to get there.
